DISTILLING APPARATUS.

Specification of Letters'Patent.

Application led September 12, 1907.

To all whom it may concern:

Be it known that I, MILTON B. BLoUKn, a citizen of the United States, residing` at 1222 /Vasliington Boulevard, Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Distilling pparatus, of whichthe following is a specification.

My invention relates particularly to waterdistilling apparatus for domestic purposes; and my primary object is to provide improved apparatus of the character indicated of simple and inexpensive construction and lhaving features of improvement providing for economical operation and for readily cleansing or flushing the boiler of the apparatus. f

The invention is illustrated in its preferred embodiment in the accompanying drawing, in Which- Figure l represents a sectional view of a water-distilling apparatus constructed in accordance 4with my improvements; Fig. 2, a section of the boiler of the apparatus taken as indicated at line 2 of Fig. l; and Fig. 3, a sectional view taken as indicated at line'3 of Fig. l and showing the detail of the means em loyed for securing the closure of the flus -pipe With which the boiler is provided.

In the construction illustrated, A represents a boiler; B, a vertically-disposed pipe which constitutes a water-jacket and inlet conduit which is in communication at its upper end, through a tube b, with the lower portion of the boiler O, a condensing-pipe aving connection with the upper portion of the boiler; and D7` a burner or heater located beneath the boiler and adjustable with relation thereto.

The boiler may be of any approved shape and construction. It is provided with a corrugated bottom a which is provided near its periphery with a circumferential channel al which is intersected by parallel corrugations 0.2. The bottom is equipped with a flushpipe a? which is located opposite the inlet l) and opens into the circumferential channel a1. The lower end of the pipe a3 is equipped with a cap a4 supported on a pivot a5. The

cap a* is provided at its edge opposite the pivot a5 with alug a engaged by a yoke a7 whose upper end is supported by a pivot as. The lower end of the yoke a7 is provided with a screw af which enables the cap a4 to be securely clamped over or against the lower end of the flush-pipe 0,3. A wind-shield alo detion.

pends from the bottom of the boiler and serves to shield the flame from the burner D. The boiler is equipped with a removable top c and is provided internally with a hollow frusto-conical member d whose base-portion is joined by a water-tight connection to the inner surface of the cylindrical wall of the boiler beneath the steam andl water outlet am. The apex of the member au is cut away to provide a central opening al which is located beneath the movable top a, thus providing for access to the bottom of the boiler.

The pipe or cylinder B is provided with an apertured upper cap b1 through which the pipe C extends and has water-tight connec- Said pipe B is provided with a lower cap b2 through which extends the reduced lower end c of the pipe C. A water-inlet b3 is provided at the lower end of the pipe B, and this inlet is controlled by a valve b4. l/Vithin the boiler at the orifice of the tube l) is a water-deflector lf which is located above said orifice and is of concave fan-tail shape, adapted to spread the water and deflect it against the bottom of the boiler when water is admitted under full pressure for flushing purposes. The pipe B is provided with an overflow tube b, which determines the height of the water in the boiler.

The boiler is supported by the pipe C and tube b through the medium of the pipe or jacket B. The pipe B is supported by brackets 67, bs, which encircle it and are supported by a plate 59 which is shown connected with a vertical wall b1", which may constitute a wall of a kitchen sink. The pipe B is provided with a collar b which rests upon the upper bracket 127. The bracket 57 has a forward extension 512 which has a vertical passage or socket which receives the stem of thc burner D. A thumb-screw 513 serves for vertical adjustment of said burner.

The burner or heater D may be of any desired type, being preferably either a gas burner or an electric heater.

The operation will be readily understood from the foregoing detailed description. Wyater is admitted to the pipe B from the inlet b3, the admission being regulated by the valve b4, according to the evaporating capacity of the boiler. Steam passes through the opening a ol the cone (L12, and a portion of the steam is condensed in that chamber of the boiler which is located above said cone, the water thus formed running oill through Aing spread by the deflector b5 over the bottom and running through the corrugations into the circumferential channel al, whence 1t escapes through the Hush-pipe. The bottom of the boiler is usually of copper, which tends by its properties of contraction and eXpansion to prevent the formation of scale, and the provision for complete flushing which is made in the apparatus insures cleanliness of the bottom of the boiler, thereby tending to economy of operation. The corrugations of the bottom provide for contact of a larger area of heated surface with the water, also. The cone (L12 serves to prevent such portion of the steam as may condense, owing to contact with the upper walls of the boiler, from flowing back to the bottom of the boiler, thereby obviating such loss as might arise from re-evaporation of the water. The adjustability of the burner D enables the hottest part of the Haine to be brought into contact with the bottom of the boiler, regardless of the variation in gas pressure which is encountered in different localities. The {lushpipe as preferably extends beneath the lever of the burner, so as to be readily accessible.

From the foregoing it will be understood that my improved apparatus is very economical in operation, simple of construction and is readily cleansed, which tends to greater durability.

In order to prevent the apparatus from turning about the axis of the pipe B, which might result in bringing the iiame in dangerous proximity to the wall which supports the apparatus, I provide the pipe B with lugs f discharge-port, a water-inlet conduit connected with theopposite sideV of the boiler near the bottom thereof, and a deflector at the orifice of the water-inlet serving to delect the water against the bottom of the boiler in the iiushing operation.

2. In distilling-apparatus, the combination of a boiler provided with a corrugated bottom and .a flushing discharge-port, a water-inlet conduit connected with the boiler opposite the flushing discharge-port, and a deiiector at the oriiice of the water-inlet serving to direct the water through the corrugations of the boiler-bottom in the flushing operation.

3. In distilling-apparatus, the combination of a boiler, a flush-pipe depending from the `bottom of the boiler near one side of the boiler and equipped at its lowerend with a withdrawabie closure, a water-pipe or jacket `having its upper end connected with the opposite side of the boiler near the bottom thereof, and a burner located beneath the boiler-bottom and extending to near said iiush-pipe, said water-pipe and flush-pipe eX- tending beneath said burner.
